Title: Axial flow air compressor
Inventor: SHIMIZU ATSUSHI
IPC: F04D19/02
Filed: 1994-04-15
Abstract: PURPOSE:To restrain break-away of the boundary layer at the rear side of a blade tip end so as to delay a stall in order to enlarge the stable operating range by providing a blade having a slit at its tip end composed of a leading end part and a trailing end part. CONSTITUTION:A slit 11 is formed in the tip end 5 of a rotor blade 3, and a slit 12 is formed in the tip end 6 of a stator vane 4. The slits 11, 12 are inclined in an air flowing direction. Accordingly, a part of air on the flank side 7 of the rotor blade 3 flows through the slit 11 thereof, and then flows around the rear side 8 of the rotor blade 3 as indicated by the arrows 13, 14. Similarly, a part of air on the flank side of the stator vane 4 flows through the slit 12 thereof and flows around the rear side of the stator vane 4. Accordingly, the break-away of the boundary layer is restrained on the rear side 8 of the tip end of the rotor blade 3, and the break-away of the boundary layer is also restrained on the rear side of the tip end 6 of the stator vane 4. Thereby it is possible to delay a stall so as to enlarge the stable operating range.

Title: Surface seal having double spiral groove
Inventor: UEIITAN REI
IPC: F16J15/34
Filed: 1993-04-02
Abstract: PURPOSE: To provide a mechanical face seal improved by using double spiral groove structure to minimize abrasion and leakage. CONSTITUTION: This is a mechanical face seal for a high speed rotating fluid pressure device arranged in a housing and including rotating and stationary seal rings having radial seal surfaces inclined and facing against each other by being engaged with each other under normal conditions. Sets of spiral grooves 71 inclined to the opposite side are manufactured on a seal surface of one of the rings, the set functions to deliver fluid from a receiver between the seal surfaces in a uniform current by a pump and the other set functions to deliver fluid between the surfaces reversely to the receiver in a backflow by the pump. Respective uniform current pumping grooves favourably cross only with one backflow pumping groove 73. Fluid pressure between the surfaces forms a clearance between them, and groove structure inclined in reverse minimizes a loss of fluid, that is, leakage.

Title: Heat-driven engine
Inventor: SUGIMOTO SAMIROU
IPC: F03G7/06
Filed: 1981-05-21
Abstract: PURPOSE:To facilitate stopping and re-starting of a heat-driven engine, by constituting a belt by use of a helical wire made of a configuration memory alloy and a straight wire made of a material that is less expanded and contracted in response to heat and disposed inside the helical wire. CONSTITUTION:A belt 2, obtained by extending a straight wire 2 made of an ordinary metal through the inside of a helical wire 1 made of a configuration memory alloy, is wound around two pulleys 3, 3. Here, since the length of the straight wire 2 is equal to the length of the loop of engine path, it is turned together with the helical wire 1 during operation of the engine, so that operation of the engine is not hindered by the straight wire 2. On the other hand, since the straight wire 2 does not cause expansion and contraction while the engine is not in operation, expansion of the straight wire 2 away from the helical wire 1 can be prevented, so that the straight wire 2 can be held on the loop of engine path. Further, in an engine in which a plurality of such helical wires are arranged adjacently to each other, engine can be re-started with ease since engangling of the helical wires is not caused.

Abstract: PROBLEM TO BE SOLVED: To provide a structure that can carry out fitting securely by preventing both connectors from butting against each other when the other connector is fitted to one connector. SOLUTION: An opening 18 of a hood assembly 10 having a sliding member 13 is mounted to a mounting hole 31 of one connector 30 out of both female and male connectors 30, 40, and the other connector 40 is drawn into the hood assembly 10 and the one connector 30 by reciprocating the sliding member 13 with guide pins 44 formed in the other connector 40 engaged with guide slots 14 formed in the sliding member 13, so that both the connectors 30, 40 are fitted to each other and both the connectors 30, 40 are separated from each other. The inside dimensions A, B, D of the mounting hole 31 of time one connector 30 are set larger than the inside dimensions (a), (b), (d) of the opening, 18 of the hood assembly 10, so that a stepped part 38 is formed on a boundary part between the hood assembly 10 and the one connector 10.  Hence, the one connector 30 never intrudes into the hood assembly 10 and thereby, the other connector 40 can securely be fitted to the one connector 30.

Title: Facsimile equipment
Inventor: YOSHIDA TAKEHIRO
IPC: H04L29/08
Filed: 1993-04-05
Abstract: PURPOSE:To make it possible to surely receive binary code information on the side of a receiver by generating a preamble signal for prescribed time between the occurrence of a signal for equalization and a binary code information signal. CONSTITUTION:At first, a data transmission request signal RS is outputted to a signal line 10a. Next, a modem 4 is set, to R transmission mode and a transmission request is performed. When a long training modem signal is outputted to a signal line 10c, an equalization is performed for the modem demodulation part on the side of a receiver and the modem 4 becomes a data transmission possible state, a transmission is terminated. A NCU 10 starts a second timer 8. Whether the buffer near the control circuit of a P/S conversion circuit 6 becomes null or not is judged and a flag or 7EH data is outputted when it is null. When it is not null, whether time is up in the timer 8 or not is judged, and when time is up, the transmission of binary code information is executed. In the binary code information, the signal showing a transmission procedure is contained and the frame constitution of a HDLC is used.

Title: Ink-jet recording device
Inventor: OOUCHI YOSHIO
IPC: B41J2/175
Filed: 1979-06-22
Abstract: PURPOSE:To eliminate the loss due to a bad recording operation by a method wherein a pressure detecting means is provided behind a filter and the output thereof is compared with that under the normal pressure so as to give a warning just when the filter is blocked up. CONSTITUTION:Between the jetting port of a nozzle 5 and a filter 22 is fitted a pressure detector 31 such as, for instance, a semiconductor pressure transducer which transduces the change of pressure to that of the value of electric resistance of a conductor. And, when the pressure of jetting from the nozzle lowers below a given value, the output from a comparator C1 gives warning outside about the blocking- up of the filter. This enables, when any trouble takes place in an ink nozzle, immediate stoppage of operation of a recording device, replacement of the nozzle, etc., thus the loss due to a bad recording operation is minimized.
